Sodium Metasilicate Pentahydrate 100%
Sodium Metasilicate Pentahydrate
Sodium Metasilicate Pentahydrate is a highly effective alkaline silicate compound widely used in industrial cleaning, detergent manufacturing, metal treatment, water treatment, and degreasing applications. Its excellent cleaning performance, buffering capacity, and ability to emulsify oils and grease make it a preferred ingredient in both commercial and industrial cleaning formulations.
This versatile compound dissolves readily in water to create strongly alkaline solutions that help remove dirt, oils, proteins, and stubborn contaminants from a wide range of surfaces. It is commonly used in heavy-duty cleaners, laundry detergents, dishwashing products, vehicle cleaning formulations, and industrial maintenance chemicals.
Key Benefits
✔ Powerful alkaline cleaning action
✔ Excellent degreasing and soil removal properties
✔ Effective detergent builder and water softener
✔ Improves cleaning performance in hard water conditions
✔ Highly soluble and easy to formulate
✔ Suitable for industrial, commercial, and household applications
✔ Helps disperse dirt and prevent redeposition during cleaning
